An HVAC system is equipment, technology, and processes that go into the heating, cooling, and ventilation of a commercial or residential building. Typical devices that fall under this definition include air conditioners, heat pumps, furnaces, air handling units, ducts, ventilation ducts, filters, and other air quality products.

Generally, there is a system in place to move warm air elsewhere, both in the home and outside. Air conditioners, heat pumps, and household stoves capture or generate heat, and then fans and ducts help facilitate movement.

The heating system is not completely isolated from the cooling system and the parts and processes that help make the two work properly often overlap.

Heat your home: how it works

Furnaces generate heat either by electricity or by burning the fuel source. The source of this fuel is most often gas, but it can also be propane or oil.

Heat pumps work a little differently when heating. It absorbs heat from the outdoor unit and transfers it to the indoor space. It does not generate as much heat as it is transferred from one place to another.

Cool your home: Here's how it works

Instead of producing cold air, which is a common myth, air conditioners and heat pumps absorb heat from inside the home and transport it to an outdoor unit, where it is released into the atmosphere.
